Add support for the Anbernic RG351V, which is a handheld gaming console
from Anbernic with an RK3326 SoC, a 640x480 LCD display, a single
analog joystick with several face buttons, two USB C ports, and
internal WiFi over USB. All hardware has been tested as working
except for the battery, which will require further modification to the
mainline rk817 battery driver before it can be used (the device was
built without a shunt resistor, and as such the battery cannot
measure current; only voltage).

Split the RG351M into its own DTSI file. The RG351M, unlike the Odroid
Go Advance, has no ADC joysticks, no GPIO buttons (except for volume
on the RG351V), a PWM vibrator that interferes with an Odroid
regulator, and different LEDs. Split the RG351M into a DTSI file
that can then be imported into the DTS files for the RG351M and a
new RG351V.

It will enable mechanism such as DTMP or IPA to work with the GPU DVFS.
